Home Box Office, Inc., owned by
Time Inc.'s
Time-Life Broadcasting unit, launched a movie-centered pay service called
Take 2 on April 1, 1979, as a companion to HBO. However, Take 2 struggled with subscriber growth and was discontinued in February 1981. HBO then announced the launch of Cinemax, a "maxi-pay" network designed to complement HBO and compete with other movie network/premium services. Cinemax debuted on August 1, 1980, focusing on theatrical films with no commercials or edits for content. Cinemax initially aired on 56 cable systems in the
Eastern and
Central time zones, with a West Coast feed launching on September 1, 1980. The network transitioned to a 24-hour schedule on January 1, 1981. Cinemax offered uncut films and was marketed as a premium addition to HBO, often bundled with HBO for a discount. In October 1983, Cinemax faced a trademark infringement lawsuit from
Tulsa 23 Limited Partnership over its promotional slogan, "We Are Your Movie Star." The court ruled in favor of Tulsa 23, and Cinemax was ordered to discontinue the slogan. As competition increased, Cinemax adjusted its programming strategy by including more adult-oriented films and launching the
Friday After Dark late-night block in 1984. The network also introduced original programming and series, including
Second City Television, The Richard Belzer Show and
The Max Headroom Show, as well as the freeform
Cinemax Comedy Experiment. Music programming was also introduced, including
Album Flash and
Cinemax Sessions; some of these music programs were simulcast for free over a national FM radio network to provide stereo audio. In February 1988, the network premiere of
Lethal Weapon became one of Cinemax's highest-rated broadcasts. On March 4, 1989, Warner Communications announced its intent to merge with HBO's parent company, Time Inc., for $14.9 billion. Despite legal challenges from
Paramount Communications, the merger was completed on January 10, 1990, creating Time Warner (later WarnerMedia, now Warner Bros. Discovery), which remains the parent company of Cinemax and HBO. In August 1991, Cinemax, along with HBO, was among the first American pay TV services to introduce multiplexed channels. Starting in 1992, Cinemax reintroduced television series development with adult-oriented scripted series, such as
Erotic Confessions,
Hot Line,
Passion Cove,
Lingerie, and
Co-Ed Confidential. Cinemax was the exclusive premiere network of several blockbuster movies, such as
GoodFellas and
The Godfather Part III in 1991,
Juice in 1993,
The Fugitive in 1994,
Any Given Sunday,
Eyes Wide Shut, and
The Matrix in 2000, and
X-Men in 2002. From 1992 to 1997, Cinemax featured daily movie showcases centered on specific genres, identified by pictograms. This practice ended in September 1997, with Cinemax adopting a simplified branding strategy that included "Max Hits at 8" and "Max Prime at 10." In February 1994, Cinemax, HBO, Showtime, and The Movie Channel introduced a
content advisory system to inform viewers about program content. A revised system with content codes was implemented on June 10, 1994. In 1998, Cinemax began offering "sneak preview" blocks for its multiplex channels, ActionMax and ThrillerMax. Classic films, once a staple of the Cinemax schedule, were increasingly featured on multiplex channels like 5StarMax. In February 2011, Cinemax shifted its focus to original programming, launching series to compete with other premium services, all of which were very popular:
Banshee, The Knick,
Hunted,
Strike Back. and to rebrand its image from being primarily known for softcore pornographic content. In January 2020, WarnerMedia announced that with the upcoming launch of
HBO Max, Cinemax would cease commissioning original programming but would continue as a movie-focused service through existing distributors. Cinemax's original programming, although available internationally, was not included in HBO Max. Len Amato, the executive overseeing Cinemax and HBO's film and miniseries division, left WarnerMedia on August 14, 2020, marking the end of Cinemax's original programming efforts. On May 17, 2021, AT&T and
Discovery, Inc. announced a
Reverse Morris Trust agreement, wherein WarnerMedia would
spin-off from AT&T and merge with Discovery for $43 billion. This merger, completed in spring 2022, resulted in the formation of Warner Bros. Discovery, led by
David Zaslav. On May 23, 2023, the merged company's streaming service was rebranded as Max. It would soon revert back to HBO Max on July 9, 2025. ==Channels==
